This guide covers the correct application of Kraft Paper Gummed Tape: selecting the variant, preparing the box, uniformly activating the adhesive, placing the strip, and final pressure. Follow these steps to achieve a clean, tamper-evident seal, with specific notes for 48 and 70 mm widths and standard and reinforced versions.
Product Specifications
The tape uses kraft paper with water-activated starch adhesive. The standard version is unreinforced and suitable for light to medium boxes; the reinforced version incorporates fibers for more demanding seals. The roll length is not listed as confirmed commercial data, so you should calculate consumption by the number of boxes rather than by an assumed length.

Step-by-step usage guide
Choose width and reinforcement
Use 48 mm for a compact seal on standard boxes and 70 mm for greater joint coverage. Choose standard for light to medium boxes and reinforced for more demanding seals.
- 48 mm: box of 36 rolls.
- 70 mm: box of 24 rolls.
- Reinforced: contains fibers; confirm with your manager for acceptance in the recycling stream.
Prepare the box
Close and align the flaps. The cardboard surface must be dry, clean, and free of dust, oil, or labels crossing the joint. The tape needs direct contact with the fiber.
Activate the adhesive with water
Evenly moisten the adhesive side with clean water. A gummed tape dispenser facilitates a regular film; if activating manually, avoid both dry areas and excess water.
Apply and press the strip
Place the tape immediately, centered over the flap joint. Smooth from the center outwards and press the entire surface so that the adhesive penetrates the cardboard without bubbles or creases.
Test the water setting and length with one box before starting a batch. A well-activated strip integrates into the fiber; if it peels off cleanly, check humidity, pressure, and cardboard condition.
Complementary Products
For repeatable work at a packing station, use the compatible dispenser from 20 to 100 mm.
Storage and Preservation
Store tape rolls in closed boxes, dry and separated from the floor and water sources. Ambient humidity can activate or deteriorate the adhesive before use. Keep the edges protected so the roll advances straight in the dispenser.
Maintenance and Care
Remove paper dust from the dispenser's path and clean adhesive residue with water before it dries. Do not apply solvents to the gummed side or leave a roll mounted in contact with water at the end of the day.
Frequently Asked Questions (FAQ)
How is kraft paper gummed tape activated?
Evenly moisten the adhesive side with clean water, apply the strip immediately, and press it onto the cardboard. Avoid soaking it or leaving dry areas.
What is the difference between standard and reinforced?
The standard version is unreinforced and is suitable for light to medium boxes. The reinforced version incorporates fibers for more demanding seals; its recyclability depends on the manager's acceptance.
Are the 48 and 70 mm variants compatible with the semi-automatic dispenser?
Yes. The dispenser accommodates widths from 20 to 100 mm, so both variants are within the compatible range.
